CHAPTER 9 8-BIT TIMER/EVENT COUNTER
214
(2) External event counter operation
The external event counter counts the number of external clock pulses to be input to the TI1/P33 and TI2/P34
pins with 8-bit timer registers 1 and 2 (TM1 and TM2).
TM1 and TM2 are incremented each time the valid edge specified with the timer clock select register 1 (TCL1)
is input. Either the rising or falling edge can be selected.
When the TM1 and TM2 counted values match the values of 8-bit compare registers (CR10 and CR20), TM1
and TM2 are cleared to 0 and the interrupt request signals (INTTM1 and INTTM2) are generated.
